Apical Dominance High
High apical dominance describes cannabis plants that exhibit strong vertical growth with a pronounced central main stem, compared to lateral branch development. This growth pattern is controlled by auxin distribution and genetic expression, creating a narrow, columnar plant architecture. Breeders working in this category often observe reduced branching and a single strong leader shoot, which influences canopy structure and training response. Plants exhibiting high apical dominance typically require more aggressive pruning or training to maximize light interception and yield potential. This trait is frequently encountered in Sativa-leaning and some landrace lineages, where vertical growth provided competitive advantage in natural environments.

Growers and breeders select for or against high apical dominance depending on grow space and training philosophy. Low-stress training (LST) and topping techniques are commonly employed to redistribute growth hormones and manage plants with this trait.
